Do you know how *Twitter following* works?

It's an asymmetrical relation from node A to node B.

{% hint style="info" %}
It works in the same way in **DMT SYSTEM**.
{% endhint %}

{% hint style="warning" %}
There is one difference: dmt node following is not a database relation.
{% endhint %}

To clarify: **Person A** following **Person B** is just a small *database entry* in central Twitter database. It is **their** social graph. They own it.

{% hint style="success" %}
There is one difference: **dmt node following** is a more dynamic property of the system.
{% endhint %}

See next section about *Internet connection monitoring* first to understand better how **DMT ENGINE following works.**
